Use this two-part accessory in several configurations to increase the focal length of the objective for high-power visual observation and lunar-planetary photography. We do not recommend the Barlow for deep-sky photos when using a scope that has a fast focal ratio. These photos will exhibit significant field curvature, which will limit the usable portion of the frame (depending on frame size). |
| The 2-element design uses special glasses to preserve the fine color correction of the main objective. The optical elements are hand-corrected and precision centered to insure that no aberrations are introduced into the system. The Barlow focal length is -127 mm which is longer than conventional types. This minimizes the divergence of the edge rays and therefore reduces the apparent vignetting common in many eyepieces (Plossls and Panoptics). The Barlow features a brass locking ring as described for the 2.7" focuser. Note the following positions and resulting magnifications: 1.7x after the diagonal |

The Astro-Physics 2" MaxBright Diagonal was designed
with several unique features to provide optimum performance and years
of use. |
Mechanical Features The diagonal is accurately square to the optical axis due to the CNC machined parts and special mounting method of the mirror. The baffles and flat black interior allow maximum contrast. It is threaded for 48 mm filters so that you can change eyepieces with ease without changing the filter. Consider these dimensions to be sure that the barrel of your accessories will not strike the mirror. When using 2" accessories, the depth from the top of the diagonal to the mirror surface is 1.85". When using 1.25" accessories, the depth from the top of the diagonal to the mirror surface is 2.25"; our 1.25" adapter adds another 0.25" height. Remember that if you add filters to your eyepiece barrels, the overall length changes. The total optical path length is 4.1", comprised of 2.75" from the center of the ocular opening to the mirror and 1.35" from the center of the objective opening to the mirror. |

The Vario Finder system is unique in that it utilizes a high quality 2-element Zeiss designed objective and an interchangeable T2 accessory system that will allow the included 45° prism to be switched with user-provided 90° prisms, or used in a straight-through configuration. Because of the exceptional quality of the optics, this finder will also be able to be used as a guide scope employing a variety of new 3rd party guiders. We are reviewing accessories for future release in order to maximize its potential as a guider. This finder assembly includes a newly designed Astro-Physics custom bracket for mounting in either of our existing Quick Release Bases (QRBASE and QRBASES-A). The bracket slides into the dovetail base and then tightens quickly with two thumbscrews. This provides a secure and repeatable method of attachment. It may also be attached to either of our sliding bars (7” SB0800 and 10” SB1000). The bracket assembly includes the bracket ring, alignment screws, and male dovetail base. The nylon alignment screws provide a quick and easy way to align your finder without marring its finish. Note: A Quick Release Base (QRBASE or QRBASES-A), purchased separately, is required for attachment. Weight: 2 lb. 1 oz. (0.935 kg) |

This stylish quick release finder bracket was developed by Astro-Physics specifically for the 10 x 60 Baader Planetarium Vario-Finder to provide a rigid, yet light weight, mounting system. However, it can be used with any finder that has a body length of at least 3 ¼” (83mm) and a diameter of between 2 3/8” (60 mm) and 2 5/8” (67 mm), allowing it to fit into this bracket with enough room left over for adjustment. This versatile bracket can be mounted in several ways:

| The bracket assembly includes the bracket ring, alignment screws, and male dovetail base. This assembly, with your finderscope, slips into the groove of the base and tightens quickly with two thumbscrews. Now you are ready to go. There are no mounting screws to get lost in the grass or snow and your fingers won't freeze as you struggle with tools. This accessory is a must! You may want to consider purchasing extra bases that you can mount permanently on your other telescopes. This will allow you to use the same bracket and finder interchangeably. Now you can attach and detach your finder in seconds while retaining the alignment. Weight: 5.3 oz (0.15 kg) |

This quick release finder bracket was originally developed by Astro-Physics to be used with our original 8 x 50 finder (discontinued). However, this bracket can be used with any finder that has a body that is at least 2 7/8" (73 mm) long and with an outside diameter of between 1 7/8" (48 mm) and 2 1/4" (57 mm), allowing it to fit into this bracket with enough room left over for adjustment. This versatile bracket can be mounted in several ways:
The bracket assembly includes the bracket ring, alignment screws, and
male dovetail base. This product originally was packaged with a female
dovetail base for mounting on your refractor (QRBASE,
see below). However, due to the introduction of the smaller radius
base, you must now specify which base you need, either QRBASE
or QRBASES-A and order them separately. |

This base mounts onto the predrilled holes of your
Astro-Physics refractor or other commercial telescope that utilizes the same hole spacing. Fortunately, the spacing between the holes
of most finder brackets is the same. The dovetail design of this base accepts these items:
|
The base is small enough that you can leave it attached to your scope. When you place it into the case, position the scope so that the base is in a corner position. Simply loosen the screws and slide the finder assembly out. You may wish to purchase an extra base to attach to other telescopes so that you can swap your finder easily from one instrument to another. If your scope has multiple finder bracket holes, you can either have multiple types of finders on your scope or have the ability to quickly switch your finder from one side of the scope to another. Please note that this base was designed to fit on mounting surfaces with diameters approximately 6" or greater. If you are attempting to attach this base to a 130 mm f6.3 Gran Turismo, please refer to the Extra Base for Quick Release Bracket, Small Radius, listed below. Note that the dovetail slot is the same for both of these bases. Weight: 2.1 oz (.07 kg) |

This base was specifically designed to fit the predrilled
holes on the smaller 4.7" tube diameter of the 130 mm f6.3 Gran Turismo, though it may also fit on other instruments with small tube diameters.
The 130 Gran Turismo has only one set of finder bracket holes since the tube rotates easily if you wish to change the position of the finder. The dovetail design of this base accepts these items:

Our male dovetail base is a versatile
accessory - an integral part of our Quick Release Finder Brackets and an essential
link for attaching other accessories to our refractors. We include this
part in every order of modified Tele Vue Starbeam (STARFMD) or Qwik-Point
(QWIKMD) finder scopes. Can be used either of the two Bases for the Quick
Release Brackets (QRBASE or QRBASES-A),
shown above, or with our 7-inch sliding bar. |
